This year, give the gift of Death

Murder, Inc. has gift certificates. How disgusting is that?

Although I can think of some slogans they could use:
The gift that keeps on giving makes giving obsolete.

Why share your stocking space?

From our family to your lack of one

For unto us a child is torn into tiny pieces and stuffed in a dumpster

What blob of cells is this...

We wish you a saline scalding, we wish you a saline scalding...

Or even a simple
Merry Deathmas!
